Thanks for suggestion. I will have to do this. Seems like a lot of trouble over an upgrade, but I'm not too surprised; I'm used to Linux. Bill

Thanks Bounder. I performed the reactivation technique described above, and it said I was still activated with the proper serial number, but I chose to Activate it again as administrator just in case. Unfortunately no joy. When I run DCS Multiplayer I get a black screen. Very frustrating. My joystick works and is set for Su25, TF51, and K4. I am running Windows 10. Any more ideas? Bill

I had the Kurfurst working fine in previous version DCS World, but after today's start the program asked me to upgrade to DCS 1.5.2.49392, which I did, but now when I try to fly the K-4, it won't let me. Instead I get to see it autofly itself when I select and Instant Mission and takeoff. F1 won't allow me to enter the cockpit. The Su-25 works fine. I deleted and reinstalled the K4 with the serial number from within DCS World, but same result. Any ideas/suggestions? Bill
